摘要： A rotatable chuck (10) is provided for use with a power tool having a drive shaft (16). The rotatable chuck comprises a body (12) comprising a rear end (14) adapted to be connected to the drive shaft (16) of the power tool, and a forward end (20) adapted to receive a shaft of a work tool, the body (12) being rotatable in response to rotation of the drive shaft (16); a plurality of jaws (18) disposed at the forward end (20) of said body (12), the jaws (18) being capable of gripping the shaft of the work tool; an adjustment ring (28) mounted about said body (12) and being threadably engaged with said jaws (18), the adjustment ring (28) being rotatable relative to said body (12); a protrusion (96) connected to said adjustment ring and being rotatable therewith; and an impact member (56) comprising an impact surface (74,76, figure 10) and being rotationally limited relative to said body (12). Said protrusion (96) is so arranged and constructed as to impact said impact surface (74,76) when the drive shaft is rotated, whereby the adjustment ring and the body are rotated relative to each other, causing the jaws (18) to loosen or tighten depending on the direction the drive shaft is rotating. The protrusion (96) and the impact surface (74,76) are separable in response to rotation of said body.
